I Application filed June 27. 1917. SertaI'No. 177.234. Renewed April 3. 1919. Serial No. 287313.

To all whom it mag concern lie it known that 1 ELLwooo Aiminnos'i, a citizen of Canada, and a resident of Gillies Depot, Province of Ontario, and-.Dominion oi Canada, have invented a new and useful Iiiiplrovement in Automatic Magazinelhonographs, of which the following is a full, clear, and exact description. v

This invention relates to sound reproducingniachines and has particular reference to atito'matic phonographs. By the term pho: nograph as used herein I wish to cover any analogous type of sound reproducing devices irrespective of the manner of operation or the specific character of record used therein.

Ai'nong the objects of the invention isto provide a self contained calbinet or casing of compact form and convenient size, as for instance one that is similar in general appearance to an ordinary domestic disk record phonograph, adaptedto carry in operative position a considerable number of selected records with means for bringin any or all of said records into playing position.

Another object of the invention is to provide a phonograph of the type above indicated with automatic selector and stopdevices so arranged that the machinewill op crate automatically to play any selected group of records one after another and then stop at the end of the last record.

Another object of the invention is to pro vide a magazine Wheel arranged for holding a number of selected records of the cylinder .type, the holding means for each record being of a character suitable for holding such record permanently without danger oi slipping, splitting or breakage.

A still further ob ect. is to provide a phonograph with improved driving facilities for the several records so arranged that each Another olo ect is to improve the means for automatically stopping the trayel of the reproducer at the end of each reciprocation thereof in either direction and to shift the same toward and from the record to provide for the interchange of the records automatically.

Another object is to provide a shifting and interchange mechanism for phonograph records operated automatically in connection.

with a pair of parallel screws having. in con- A ing cards or legends bearing the name, num her, or other identifying means for the sev-.

eral records and means to drive one of said parts from the other with the same angular trolled pointer cooperating with the indicator roll tosh'ow to the observer at any time the precise record being played'or selectedlVith the foregoing and other objects in View the invention consists in the arrangement and combination of parts hereinafter described and claimed, and while the invention is not restricted to theexact'details of construction disclosed .or suggested herein,

still for the purpose of illustratinga practical embodiment thereof reference is had to the accompanying drawings, in which like reference characters designate the same parts in the several views, and in which Fi comp ete machine on substantially the line 1 re 1 isa vertical section view of the 1-l of Fig. 2, and looking toward the inside: l

Referring now more particularly to the drawings 1 show a casingor cabinet 20 of any suitable size or design and including removable right andleft side panels21 and :22

respectively, a bottom 23, an upper deck :24,

an intermediate deck and a lid 26 hinged at 27 to the upper end of the back panel 28. Secured in any suitable rigid manner upon the frame or bottom 23 are right and left upright standards 29 and 30, made pref- "erably of aluminum and extending updeck 25.

wardlyparallcl to each other .to abo'ut. the This deck is supported directly upon theupper end of these standards, and

a pair of standard extensions 31 and 32 are erected. upon the prin'iary standards and reach abouttotlie level of the upper deck 24. also in parallel relation to each other and approximately midvay betwecii the front and rear of the machine. All of these stand:

the operating parts.

33 indicates the'inain supporting shaft of the magazine wheel journaled horizontally and transve scl y of the machine in rightand left anti-friction bearings 34 and in the primary standards. To one end of this shaft is connected a spi'ocket'wheel 36 and within the space between the standards is secured the magazine wheel 37 close, however, to the inner face of the primary standard 30. This wheel is constructed of any suitable skeleton form but having two essential features; namely, a grooved run 38 for a drlving belt" 3!) and a web 40 within the rim provided with a series of holes 41 arranged concentric with the axis of the shaft 33, each of the holesliaving a short groove or notch 42 at its front leading rearwardly toward the straight rear wall of the hole. See'Fig. 17; A c rcular series-of parallel spindles43 are clamped rigidly in the rim38', and on each spindle is journaled through suitable anti friction bearings 44 and 45 a record holding mandrel 46 preferably faced with felt or some other suitable resilient material and of slightly-tapered form toward the free right and yet without danger of splitting or rupturing the cylinder on account of change of temperature or other conditions. Endwise displacement of the cylinder is prevented by means of an elastic rubber ring 48 fitted upon the free end of the mandrel and against the end of the cylinder.. The free end of each spindle is reduced where it passes through the bearing 44 and is fitted with an adjustment nut 4!.) just beyond which the end of the spindle is tapered forming a small cone with which is adapted to cooperate an endwise slidable bearing cup50 the mandrel and record steady while that particular record is being played. See Figs. 2

2 and 4. The left end of the mandrel constitutes a hub having formed on its surface a spur gear 51 and a friction run 52 close alongside thereof, the effective surface ofthc friction rim coincidingwith the pitch circle of the gear. The. magazine wheel .is normally held fixed from rotation by means of a locking pin' 53 extendinginto one of'the holes 41.. Tll lS'plll is fitted slida'bly in the. standard 30 being supported in a pair ofa inner-and outer platcs l'i-l and between niounted in the standard 29 and whose func- Y tion is to hold the otherwise free end of' of the axis thereof.

which is arranged a spring 56 tending to hold the pin in looking position,.sa1d spring acting against a sl'1oulder57 at one end and theplate at the other end. See. F10. 17.

indicates a cylindrical fired guide rod spppforted 1n andlextending between the s andards 29 and 30 above the magazine wheel and just back of the vertical plane.

This rod constitutes 61 in which are slidably .an d-non-rotatably fitted shoes (32 and 63 respectively. Said hub also carries a pairof leaf springs 64 and (35 hearing resiliently upon said shoes. SeeeFigs. 9 and 10. The carriage 59 is provided at its ends with radial notches 66 and 67 forming offsets or shoulders 68 and 69 respectively. Just back ofthe rod'58 and parallel thereto are a pair of power screws arranged with their axes in the same vertical plane, afeed screw 70 andza return screw 71, with which .said shoes 62'and' 63 respectiyely ,cooperatein alternation. The free end of each shoe opposite its spring is shaped to coiiperate with the thread of the corresponding screw. These-screws as im dicated are adapted to be driven constantly inopposite directions, the fcedscrew being designed so that its rate of rotation and pitch Wlll correspond exactly to the record groove on the cylinder 4'? and the return screw is formed with a quick pitch and adapted to rotated at a comparatively high speed preferably in antiand hence is journaled frictlon bearings. g

The reproducer point 1s indicated at 72 and is carried-by a-body 73, supported on a, spring 74-, connected by a screw through a rubber washer or gasket (5, wlth the main portion of the carrlageto prevent the transmission of mechanical sounds, a7 felt ring 75 also being interposed between the carriage and, the attachment for the tone arm. Thefront end of the carriage comprises an upwardly and forwardly projecting finger 76 supported upon a horizontal transversely extending cam *bar 77 journaled at itsends in-the standards 29 and 30 for rotation through approximately 90degrees. Fig. 10

= shows this bar in position for supporting the carriage in normal playing position with the feed screw 70 acting through the shoe to traverse the carriage toward the right. When, however, the cam bar is llfted'or ro- 'tatedin a clock-wise, direction it will,- actin}; through the finger 76, lift the reproducei-po'int 72 from the record and bring the shoe 63 into engagement with the quick return screw 71. The screw is provided at the right hand end with a groove 78 into 64, Which-automatically stops thetraversing effect of this screw. Similarly the return screw 71 1s provided at its opposite end with a groove 7 9 fora similar purpose. A horn 80 projects through and is supported by the rear portion of the deck 25,

the bell of the horn being located just within a suitable scroll or grill 81 at the upper front of the cabinet. The'reproducer is connected to the smallend of the born by means of a suitable'tone arm 82 of variable length, the same bcingshown as of. telescopic parts connectedby universal ball Joints 83 and Site the repro'ducer and horn respectively so that while the reproducer carriageis being moved along the support- 1n" rod 58 the tone arm accou'mmdates itself accordingly in length and position. .This tone arm also accommodates itself tov the slight degree ofrotatlon of the carriage around the axis of the rod 58 as controlled.

by the position of the cam bar.

Any suitable means maybe provided'to U actuate this machine, but for practicalfp-ur poses I employ an electric motor M secured i to and suspended beneath the front part; of the deck 25 through soft rubber washers 85 able noises. See Figs. 1 and 2.

'to eliminate" the transmission of objection 86 indicates a governor shaft journaled horizontally of the machine and substanmotorshaft 88 by means of a belt 89 acting v, I

over a pulley 90. This belt as are also the other principal belts is preferably made of round rubber or any other suitable magovernor is intended to operate. The governor is mounted upon the shaft 86 and comprises a hub 91. keyed at one end and a hub- 92 splined itothe other end in proximity "terial and of a practically noiseless nature. i The motor is so designed as to operate the y shaft at .a slightly higher speed than the. i

to the pulley .90. A spring 93 is coiled about theblmftbetween the hubs acting at one end against an adjustable nut 94 and at the other end against the slidable huh 92 tendingto hold the face of the hub 92 against the driving face of thepulley 90.

Suitable friction is, provided-for between these two facr-s through cork, or similar plugs carried by the pulley and forced toward the governor hub by means of light coil springs 95. Since the drivingpulley 90 is journaled on the shaft 86 for independent rotation, the end thrust incident to the action of the spring 93 is borne by an anti-friction thrust bearing 96,. one por by means of asuitable lock nut 97. Cention of which is locked in desired position trifug allyoperated balls 7 98 are carried by leaf springs 99 having their ends connected to the hubs 91 and 92. WVhen the speed of rotation of the 'governor is suificient these balls flying out, will withdraw the slidable hub 92 from the drivingpulley against the force of the spring.93, according to the adjustment of the nut 94:.

Keyed or otherwise secured to'the outer end of the shaft 86 is a pulley 100 from which a'belt 10]; leads to a larger pulley 102 (see Fig. 3) fixed-to a short jack shaft 103 journaled in the standard 30. Direction of movement of the belts and allied parts is indicated by arrows on the several figures.

On the inner end of the .jack shaft is secured a combined spur and friction pinion 109 is fixed upon the jack shaft between the pulley 102 and the standard .30. A train of speed reducing gears 110, 111, 112 and 113 transmit the power from the pinion 108 to the feed screw 70 at a moderately low speed, depending upon'the pitch of the screw. I

The return screw'7l is operated from the ulley groove 114 formed in the governor liub 91 and a belt 115 operating over a pulley 116 fixed to the return screw, this action being more nearly direct from the motor than the means for driving the feed screw,

' is materially more rapid.

e 119 will be brought into driving-.engage-' 117 indicates a counter shaft journaled in 3 the standard 30 above the jack shaft. On

the outer end Jof this counter shaft is 'fixed a spur'gear 118 meshing with anidler pinion 119 carried on a bell crank 120 journalcd around the bearing for the shaft. This pinion 119 is held normally out 'of mesh with the gear 109 by means of a spring 121 holding the longerarm of the bell crank against an adjustable stop 122. When, however, the bell crank is swung down by any suitable means until stopped by another adjustable stop 123, the pinion ment with the'ge'ar 109.. By this means then the counter shaft will be rotated from,

the jack shaft. Onthe inner end of the counter shaft is fixed a pulley 124 havingagroove in the plane of the groove of the magazine wheel and from whiclrtlle belt 39 is driven for the purpose of rotating the magazine wheel when desired and the pin 53 iswithdrawn. An idler pulley 125 carried by an arni 126 hung from a portion of the bearing for the cpuhter shaft, bears upon the belt 39 to maintain uniform ten is grooved for three records, those at the ends i being about four minutes long: and the one between them about eight minutes. This is mentioned simply to indicate that the individual records on the several cylinders may be of a great variety of'lengths as Well as 0 ii musical or literary character. At 127 I incate an index roll, shown herein as mounted for rotation around a horizontal axis in theupper part of the machine parallel to the axlsof the magazine wheel. The shaft 128 35 for the indicator roll is'journaled in bearing boxes 129 and 130 supported primarily upon the standard extensions 31 and 32 respectively at about the level of the upper deck 24:. The roll therefore lies in an 0 ening 131 in the deck 24, the upper half 0 the surface of the roll being Visible above the. deck. 132 indicates a semi-cylindrical dust guard surrounding the lower half of the roll. The construction. of the roll 127 will be understood best from Figs.- 12, 13 and 14 and is in" the nature of a hollow cylinder, the shell 133 of which is provided at the left 7 end with a circumferential series of longitudinal'parallel dovetail grooves 134, in each of which is slida'bly mounted a mechanical stop 135, the outer end of which is beveled on its front face at 136 and adapted to occupy any one of three different positions represented in Fig. 14 as A, B and C. Each of these stops is provided'with a finger piece 137 projecting radially inwardly therethrough, the inner end of which projects through aslot 138 in the shell 133 and between a pair of springs 139 fixed by screws 1'1'0 or the like 140 to the inner surface of the shell through plates 141; The springs of each pair areprovided with a series of pockets (1, I and '0 (Fig. 15) correspondingto the respective positions A, B and C in which said springs are adapted to'hold-the stop in practice. By grasping the linger piece 137 the operator may easily. slide the stop from any position to the next forcin the stud or pin from one pocket to the nextlZO- for it to beheld automatically by virtue of the springs. The dovetail groove 13 1.for each stop holds the same securely from tilting or rotation with respect to the shell. The shell133 of the indicator roll is provided 126 with as many of these stops .135 as there V are mandrels 46 for record cylinders, and suitable iilentifying means will be provided for the groom-s of the indicator roll to 'correspond to the several record lnandrels.

Likewiseiii longitudinal alinenient with each I of the stops 135 is provided a space forthe name, number or other identifying means for'the record selections of the cylinder pertaming to such groove and stop. As indicated furthermore in Fig. 12 the length of the several identification cards will be varied according to. the length ofthe corresponding records so that a suitable pointer 142 operating over or along the face of the roll 127 and directed to one of the identification cards 143, will show. precisely the name of the selection being played, the length of the record, and the portion of the record being rendered at any particular time. Said pointer 142- is carried by a slide 144 movable along a pair of guide rods, 145 either by the operator's fingers applied to the handle 1 16, or automatically. The shank of the pointer 142 projects upwardly through a slot 147 in front of and parallel to the opening 131. The slide 14:1 is adapted to travel longitudinally along the indicator roll in the same manner" as the reproducer carriage 59 travels I longi; udina'lly along the guide rod 58 andin the same direction. The means vtoeffect this resultis shown best in F ig. 11 as comprising a cable 148 attached to opposite sides of the reproducer carriage and attached also to the slide 144,- said cable operating over a series of-suitably located direction pulleys 149,150; 151, 152, 15s and'154; A spring tion which will 'be identified by the particular card 143." indicated by the pointer. WVhen, however, the carriage is reciprocated automatically in the, usual way the index pointer will be moved therefromin a corresponding direction through the cable 148. A sprocket wheel 156 of the same'diameter as the Wheel 36 is secured to the end of the roll shaft 128 and a link belt or roller chain, 157 operates from one of these sprocket wheels to the otherso that the indicator roll is rotated from the magazine wheel and at the sameangular velocity to insure correspondence of position between eachrecord cylinder and its index means.

-' Iv will now refer-to a preferred en'ibodimentor arrangement of controlling devices,

- most of which are automatic. Among these controlling devices may be noted from Fig. 17 the followingi A circuit plug 158 with asnap switch 159 through which a current may be supplied to the motor through a and 171 respectively, the contact 169 bein g' leads thereto-from the contact point 184, .comn'iunication' being through the switch magnetic cut-out 160 which-mayb ontrolled either by a three wire extehsioncp'rd 161 with a pair of contacts 162 and 163for hand operation from any desired distance from the machine or-otherwise, a wire 162" leading from contact 162 to the cut-outl lG O. I show also a series of electromagnets identified by the characters'm m m, m, mi. and m. The magnets m and m are t ranged in parallel, while the magnets m and m are arranged in series. I show also a plurality of switches and contacts 164, 165, 166, 167, 168, 169, 170 and 171,=ariy.,. or all. of which are preferably adaptedlffio make andbreak submerged in oil to ventdangerous sparking. As an instance of an oil receptacle for thispurpose reference is had to Fig; 13 showing at 172' ahoil container for the pairs of contiicts1i69, 170 and 171. Making further reference to Fig. 17 I show a control drum 173 beariii g on its surface a series of stepped contacts 174, 175, 17'6,"and 177. See Fig.' 16, retail m elevation of this control drum to the axis in which is fixed a hand controller 17 8through v which thedrum may be rotated in a clockiwise direction, through about 90- degrees against the force of a spring 179 connected my to an arm' 180 tending to hold the drum'iii W the normal position indicated in Fig. Again, I'indicate at 181 a puslrhuttoii adapted to break the contact at'167'i'a'nd make the contact at 168against the force of a spring 182 which holds the contact closed at 167 under normal conditions. Fu'r f 9 thermore I provide a hand switch at adapted to make contact at either 184: or 185) The principal wiring, indicated inv Fig. 17, will be identified as follows: From the motor M which gets its power through; the main line wires 186 and 187, thereby tvpify i ing any suitable SOLII'CQZOf electrical energy the current is conveyed through the trui'ili lines 188 and 189 to and through the sever; connections. From the trunk line 188 a branch 190'leads to a pair of contact bars? 191 and 192 pertaining to the contacts 169*" normally closed and the contact 171 bein' normallyopen. Said bars 191 and 192 ai both pivoted to a bearing block 193. See?" Fig. 13. A fixed contact spring 194 carries? a stationary contact at 171 and a wire 19 183 and wire-196 to the magnet 197 ofgthej cut-out 160. A pair of hell crank mechani cal contact devices 198 an l199 are pivoted" to a bracket200 just in front'of the field: of action of the mechanical stop slides 135, said bell cranks being provided with heads' 201 and 202 respectively adapted to coiSp'er-f? ate with the sli les1l35 in accordancewith the B and C positions thereof;- The heads just referred to have beveled faces against normal A position.

is connected by alink 203 with the contact,

bar 191, and the other bell crank 199 through a link 204 with the normally spaced contact bar 192. These bell cranks are held in 'position to be engaged by the beveled faces of'the contact slides by virtue of a 1 spring 205 acting toward automatically by an adjustable stop 135 is set for the only will be encontact bar will be 206. If the contact slide B position the head 201 gaged thereby and the lit'ted, breaking the contact at 169 and completing the contact 170. The contact at 169 is connected to wire 207, the latter leading to the contact 165 thence through a wire 209, magnet m and wire 210, back to the other trunk wire. The armature 211 of said magnet m is connected through a flexible line 212 leading over a direction pulley 213 to the outer end of the locking pin \Vhen the magnet energized the pin is accordingly withdrawn from locking position setting the magazine wheel free to rotate. This pin, however, carries an arm 214: which carries the movable part of the contact'lfit closing the contact throughthe wires 215 and 216 through the magnet m, wtre'2l7 and magnet m to the other trunk wire. The circuit is completed at the contaet'165, operation of the carriage 59 when it reaches the limit of its retm-n movement, the shoulder 69 of the carriage at this time striking against a .lug 218 earried by a sleeve 219 slidable on the supporting rod 58 against the force of a spring 220. This sleeve carries a plunger 221 which reciprocates through the standard 30 and carries the movable part of the contact 165 insulated from Thesleeve is held from rotation not only by the plunger 221 but also by a stop pin 222, the latter of which limits its'inward movement under the force-of the spring. As shown in Fig. 9 the carriage is just completing its return moven'iont and about to close the contact at 165 and thereby energize the magnet m The moment, however, that the carriage drops into playing position the shoulder 69 moves C1I'(t1ll'lf8liltially far enough to allow the lug 218 to drop into the notch 67 setting the sleeve free to break the contact at 165 and effecting the subsequent breaking of the circuit at 166. The magnet m remains energized until the contact 170 is closed and this is not closed until the contact 169 is'broken. When the contact 170 is closed the wires, 263 and 262 energize the magnet m. The

interval of timebetween the deiinergizing magnet m and the entering of the at the p I pin 53 into the hole 41 is -very brief, the

instrument stop at the the other parts of the device.-

-As the magazine wheel has groove 42 on the web 10. Except as just stated the pin ordinarily does not contact against 'tlie web 10. See Figs. 19 and 20. The. rotation of the magazine wheel 37, acting through these sprocket wheels 36 and 156 and chain 157, controls directly the operation of the contacts 169 and 170, and indirectly the contacts 165 and 166. This latter is effected bv the head 201 on bell crank 198 riding over any slidable contact 135 'that is set at the B position.

While the contacts 135 are set at A posi tion, the contacts 169 will not be broken and hence contact 170 will not beclosed, so that the record corresponding to this contact 135 will be passed. 'This is true accord i'ngly of all contacts 135 set .,at A position. The magnet m remains energized during this movement.

Considering the case where only one contact 135 is set at B position, the magazine Wheel will be rotated a full revolution or until this contact comes in engagement again with the head 201' when l othe recortl corresponding tothis contact will be played through and again repeated. After the contact 165 is closed the magnet no will remain energized until the contact 169 is broken, but this latter contact cannot be broken until astop 135 is set at either its B or position.- While the case just cited would be unusuahyet if it werc'dcsired to have; the end -of such record all that would be necessary to do would be to set the switch 183 on the contact 185 which would cause the stopping of the in; strument at the cadet the rotation of the magazine wheel. This is the principal use of contact 185. T he contactlS-t performs a similar function at the end of a group of stops placed at the B positionand when the next one is set at the C position. The foregoing are ,the only uses of the switch when used in combination with the stops 135. Reverting again to the stop 135 raising the head 201 and causing the opening of the contact 169 and the closing of the contact 170, the closing of the lattercontact causes the operation of the magnet m" and the dropping of the carriage 59 into playing position, this movement releasing the sleeve'219 and opening the circuit for the magnet m at 165. This action takes place as soon as the contact 1'70 isclosed and be-, fore the magazine wheel 37 has been stopped by the pin entering the groove 40 and hole 41, when the circuit for both magnets m and m will have been opened at 166, come to rest the bell cranks 198 and 199 will have riddenover the stop 135 and been brought to their inactive position by springs 205. In thisinac:

tiveposition contact 170 isopen and con act.

the

- tion is relatively slow.'

v steady the'free end of'the spindle 43, the

m stress 169 is closed, in preparation for the next cycle of operation. If the contacts 165 have not been broken, by reason of the lug 218' entering the slot 67 (see Fig. 9) the carriage 59-would not have had time to move to the right and open the contact 165, since the travel ogt-the carriage in the playing posi- The sleeve 219" is provided so that the contact 165 will always be opened before the contact at 169 is closed, after changing a record. This prevents repeating the operation of changing a record before it has been played through. It is intended to adjust the contacts so that the contact will be opened before the magazine wheel has actually come to rest and is locked in this position for playing the next record. In other words, the contact 165 will be opened before the head 201has ridden over contact 135 and brought back to its normal position closing the contact 169.

The ,n'iagnet m is supported upon the standard 29 adjacent to the slid able" cup bearing 50. A rock shaft 223 'is ournaled in bearings and carries on its outer end a pulley 224 and has fixedto its other end an arm 225, the upper end of which is seated in a notch in said cup hearing. A spring 2-26 acts upon the arm tending to hold the cup bearing position to support and arm oscillating around the axis of the" rock shaft intheplane of the axis of the spindle.

The plunger 227 of the magnet m is con nected to the pulley 224 by a flexible line 228 and is so -arranged that when the magnet is energized through the closing of the circuit at 166 the cup'bearing' is withdrawn endwise from the end of thespindle to permit free movement of the magazine wheel,

the bearing coming back again to its normal steadying position by virtue of the spring 226 when the magnet m is den'ergized and after the magazine wheel has been given the desired amount of rotation. I

The magnet m is the means I provide for shifting the gear 119, see Fig. '3, so as to initiate the rotation -.'of the counter shaft 117 and the rotation of the magazine wheel from the motor as previously. set forth.

The magnets m and m being connectedin series are-energized and deinerglzed s1mul-' taneously. The energy of the magnet m which controls the circuit of themagnets m and m ismaintained so long as the contact 165. is closed, and this condition obtains until the cam bar 77 and reproduc erparriage are lowered to playing posit1on,- or until the spring 220 is permitted t force the sleeve 219 toward the pin 222.

Referring now to Figs. 4, 5 and 6 will describe the means for controlling the rotation and position of thecambar 77. 229

indicatesa double pulley fixed to the right hand end of the cam bar and provided with a flange 23Q 'having a pair of notches 231 and 232-sl1own"-as arranged opposite each other and havingshoulders facing in opposite directions circumferentially. A spring pressed pa-wl 233 acts normally in the notch so as to limit the downward and forward rotation of: the cam bar under the nor-' mal tension of a spring 234 connected through a line 235 secured on the front face ot thep'ulley 229. In theother portion of the pulley is: connected another line 236 which leads upwardly over a pulley 237 to the armature238 of the magnet m The force ofthis magnet is sufficient tolift the cam bar and rot-ate the pulley and the bar through a one quarter rotation where it will be locked by means ofa dog 239 to which is attached a spring 240 tending'to snap the point of the dog into the notclr232. The

arn'iature 241 of the magnet mis attached to the dog 239 for the-purposeof' releasing this dog against the force of the spring 240 when-the cam bar isjto be lowered and the selection is to be played; The magnet m may be called the starting magnet. The active position of the dog 239 is'the one in w-hichthe carriage is operating-inits return movement with the shoe 63 in engagement 1 with thes'crew 71. Abovethe notched flange 230 is located a pawl 242 the point of which is held up normally by means of a spring 243 so as hot to resist the full quarter turn of the pulley. FThe armature 24% of the magnet m is'connected to this pawl through a lever 245, and link 246 so as to bring the point ofthe pawl into the notch 231 so as to limit the rotation of the pulley to its one 17 I show a' lever 247 which by virtue of a leaf spring 248 normally holds the movable part of the contact 164; open. Thevfree end a of this lever lies in the path of the shoulder 68 at the right hand end of the carriage 59 while the carriageis making its, playing movement so thatat the completionof this movement'- ofthe carriage the contact is magnet m through wires 249, 250, and 251,

for magnet m through wires 249,250 and" 268', contact 167 and wires 252 and 251. The moment, however, that the reproduoer is lifted theff-i'ee end of the lever 247 snaps into closed at 164 completing the circuit through V accumulated becauseof thejaction-of there- 1 producer point. This operation takes place automatically each time the carriagecompletes its playing movement through the automatic closing of the circuit at 164:, but

.fieXible portion 258 which leads through the .reproducer carriage with a nozzle 259 directed to the reproducer point. When the. magnet m is energized its'plunger piston 254 forces a puff-of air through the flexible tube and nozzle to blow off-the fuzz. The bottom of this air cylinder is provided with a suitable buffer 260 to prevent noise and the sticking of the plunger.

The starting magnet m has lead wires 261, 262 and-263 adapted to complete the circuit therethrough through the contacts 174 and 170 when the contact bar 191 is lifted by the mechanical contact 201 with the sliding stop at the B position. The contact 185 is only to operate when it is desired to have the instrument stop after the record in position has been played through and another is brought into playing position. In'starting the instrument again all that is necessary is to open the switch 183, or off of contact 185, and start the motor through switch 160.

Referring now again to the controller drum 173, see Figs. 16 and 17, itwill be noted that the contact 174 is normally closed while the other contacts 175, 17 6 and 177.act

successively to close their respective pairs of contact springs on rotation of the controller drum and the breaking of the contact at 174.

. This controller drum is designed to be operated primarily by hand forthe selection of certain records. When the contact is broken at 174 the magnet m is dead. When the contact 175 is closed the energy from the trunk wire 188 passes through the wires 264 and 265 through the magnet m which fixes the stop pawl 242 to check the cam bar and carriage at mid position so that the operator by grasping the finger piece 146 may shift both the indicator pointer and the carriage freely. This condition of the magnet m obtains also while the contact 176 closes its circuit through the wires 264 and 266 to energize the mag-net m to lift the carriage through the wires 252 and 268. The final contact 177 of the controller drum closes its contact through the wires 264, 208 and 209 to close the circuit through the magnet m providing for the rotation of the magazine wheel until the desired record shows up on the index card and when the controller handle 17 8 is brought back to its normal position the contact 174 will be closed so as-to initiate the playingof the record thus sea fuse replaced by the lifting of the cover.

The purpose of Figs. 18, 19 and 20 is to illustrate the relative positions of the bell cranks 198' and 199 with respect to the slid-.

able contacts 135, the locking pin 53, the groove 42, and the hole 40 in that part of a cycle where they operate to stop the magazine wheel 37 and cause the instrument to start playing the-record just brought into playing position. It will be noted that the head 202 will have to'ride up on the slidable contact 135 higher to close the contact 171 than the head 201 does to close the contact 170, thus'retardin 'the action of head 202 so that the contact 170 will have performed its function before contact 171 has opened the circuit at 160. Fig. 19 shows the point at which the magnet m is intended to be deenergized, the pin 53 being just about'to enter the groove 43. Fig. 20 shows the relative position of the locking pin to the hole 41 .whenthe contact 166 will be broken.

By. way of further explanation of the mechanism hereinbefore described andwith reference to Fig. 17, if the switch 183 be placed on contact oint 184-whi1e the instrument is in operation and with allthe stops 135 at A and B positions, no effect will result, but, if one of the stops 135 were set at C "position then when that particular record comes into playing position the head 02 riding over such stop would operate the contact 171 to open the switch 160 and stop the instrument. rent will be led from main 188, by wire 190, arm 192, contact 171, sprin 194, wire 1'95, contact 184, switch 183, wire 19.6, magnet winding 197, and by wire 197 leading to the 1 To accon'iplish this a cur other main 189. It will thus be seen that the switch contact 184 is not absolutely essential but/is included to make theoperation more flexible. The contact 185 is necessary to stop the instrument at the end of each record when desired to operate the machine this way, this function being the only reason for playing it as indicated. To operate the cut-out 160 the current willbc led from main 188, by wire 190, arm 191, contact spring 170 to which wire 263 is joined, branch wire 185 from to contact 185, switch 183, "wire 196, magnet winding 197, and wire 197 "tothe other main 189 or to 251. To use the extension wire 161 to start or stop the instrument it is necessary to place the switch 183 on its elf position as shown in Fig. 17-.

either their B 01"C osition as is done P when Setting the instrument to play selected records as explained below. Supposing that the instrument is stopped, stops 135 being set as desired, switch 183 off, and the instrument connected to the mains by the plug 1.58

and switch 159 on, it will only be necessary for the operator to take the exten- 'sion cord 161 to whatever place he wishes tobe and press the contact 162 to start the instrument; and when he wants it to stop he presses the contact 163. In the stopping action the'currentwill be led from the upper.

through contact 163 and wire 163 right live terminal of the switch 160 by wire 162' common to both contacts162 and 163,

connect- 7 ing it to wire 196, to magnet windin 197',

, andthence to the other main 189.

starting operation the current will pass,

a net winding thence to the upper left live terminal of the switch 160, completing the stops to'play the same automatically it will;

through the commons connection 162 by closing contact 162, to the closing coil magcircuit. The purpose of the extension cord 161 is to relieve the operator from the necessity of leaving his place to start or stopthe instrument when it is desired to use 1171501 playing only intermittently, the instrument playing automatically while in operation.

To select a number of records or to set the be necessary to see that the switch 183 is off hand means to be tor is started grasp and the plug 158 connected with'the switch 159 is on andthen closing the switch 160 by means of the contact 162 or by the other provided. When themohand and move the same ently to the position of contact 176, the. e'ft hand holding the "handle in this position while the right hand is used to set the desired stop 135'. When all of the stops accessible have been thusset the left hand is then usedto bring the controller to the position of contact 17 7 again to start the further rotation of the ,index cylinder 127 and so on until all of the desired stops'have been set. The act of bringing back the controller 17 8 to the position of contact .174 will start the instrument playing the records selected.v If. a particular selection is desired the controller will be taken hold of at anytime to rotate the index roll far enough so that by bringing it to the a position of contact 17 6, the rotation will stop at the correct record, and while the controller is still held at 176 the handle 146 may be grasped in the 'right hand and the-reproducer thereby raised at thecor'rect starting point of, the, particular record selected by meansof 'the'indicator 142 and the legends 143, the legends having marks to indicate the" exact ength of the selection. After this adjustment is effected withthe con-- troller brought, back to the contact'174 the the handle 178 in the left,

instrument will be automatically started to play that particular select on. In moving the indicator and reproducer from side to side in placing'the indicator it is not neces-" sary to move it so far as to close either of the electrical contacts 164 and 165 at the end of its travel. These are held open by springspand requiremore pressure to move the indicatorythus showing the operator that the reproducer is against one of the contacts. The playing point of a record starts at the point where the carriage 59 comes in contact with sleeve 219, so that it is never; necessary, in the hand selection of records',.to move the carriage so far to the left as to close the contact 165, however, no

harm would result by such closing of the contact 165 other than the undesiredrotation of the magazine wheel, and in like manner if the contact 164, at the right were closed no harm would result.

- :To tracethe connections from the use of the controller, the motor being considered as runnin and the indicator being at the end 'of a se ection other than the last one ofa series, bringing the controller'to contact 175 .opens the circuit for magnet m at 174 and closes the circuit for magnet m" through the wire 264, contact 175, wire 265, magnet m,

and wires 261 and 251 or 189. This action' limits the rotation of the cam bar 7 7 so as to free the shoes 62 and 63 from the power means and allowing for free movement of the reproducer through the handle 146 when the controller is rotated to the contact 176, 7

'to close the circuit for the magnet m", thus startingthe rotation of'the magazine wheel and index roll, which operation will continue as long as the contact '177 is closed. As soon as this contact 177 is opened the pin'53 will enter the next'locking hole 41.

After the circuit is thus broken, because in using the controller the contact 165 will be open, the instrument will not start to play to bring the cam bar 77 back to playing position. I p p from contact 177 to contact 176 it is then brought to 174 when the instrument will again play automatically. Inusing the controller the switch 183 will alwaysbe open tuntilthe contact 176 is opened which cuts 'out the magnet m and allows the spring 234 After the controller is moved 7 25 will both ride over,-the.topvjiofethe stop 1353; and-are b'roughtt-"to their normal inactive controls.
